Project Summary
A knowledge gap exists concerning the distribution of metals and metalloids among the various size fractions of airborne particulates, including aerosol. This information is critical for several research questions, e.g. i) to improve atmospheric transport models required to be able to estimate the atmospheric deposition around point sources; and ii) to develop procedures that can be used to discriminate between the various possible natural and anthropogenic sources of particulates and wet deposition. A major point source of metals and metalloids to the atmosphere is the emission from pyrometallurgical smelting operations; this project will have the opportunity to sample and study these particulates using a variety of chemical analysis techniques. A particular focus will be on new procedures for the small amounts of size-fractionated material that the sampling protocols will be recovering.
